The wallpaper on the left of the bookshelf is changeable. You can download more beautiful wallpapers from our website (http://WWW.teamonesoft.COM) besides those defaulted when installed. Import the wallpaper files (.BMP files) into the subdirectory "skin" in the installed directory, then click "Tool">"Wallpaper" to choose a wallpaper you want.
You can also make wallpapers by yourself. CUT an image into 70*268, save as 256 color or above, as bitmap files (.BMP file), then copy it into "skin" folder in the installed directory.
